Xen users - Jun 2009 - domU boot failure with Xen 3.4.0

My domU (32-bit NetBSD) is running without any problems on 64-bit Debian 5.0.1 
dom0 with self-compiled Xen 3.3.1. I upgraded our secondary dom0 to 3.4.0 (with 
2.6.18.8 kernel) and started my domU but it panics early in the boot.

I just tried Xen 3.4.1 on my Debian 5.0 dom0 but my NetBSD/i386 5.0.1 domU still
fails to start. This domU works perfectly on 3.3.2 dom0. Any ideas?
